The 'weakest link' in the aging proteome

Proteins are the chief actors in cells, carrying out the duties specified by information encoded in our genes. Most proteins live only two days or less, ensuring that those damaged by inevitable chemical modifications are ...

Tissue in trouble calls in reinforcements to restore health

Northwestern University scientists are the first to discover a cellular process used by animals when a tissue is stressed and in molecular trouble from the expression of misfolded and damaged proteins: The tissue at risk ...

Study sheds light on genetic 'clock' in embryonic cells

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating ...

Trifunctional molecule decodes cellular communication

(Phys.org)—How does one define the factors on the surface of human cells to which a molecule of interest binds? This question is typically hard to answer. Researchers of ETH Zurich have developed a new technology that enables ...

Important aspects of signalling across cell membranes in plants

(PhysOrg.com) -- Every living plant cell and animal cell is surrounded by a membrane that helps it communicate with other cells and the outside world. These cellular membranes contain receptor molecules that serve as the ...

First curved data link side-steps key 6G wireless challenge

Next-generation wireless signals will no longer emanate indiscriminately from a base station as is the case now but will likely take the form of targeted directional beams. However, any physical interference—an object or ...
